Use GtkFileChooserDialog only when we need previews, default to
NativeFileChooser otherwise.
GtkFileChooserDialogs have a long list of issues, so lets only use it
if we gain something from it.
Flatpak should only run NativeFileChoosers because its sandboxed and
this is needed for security purposes. As a result of that, Flatpak Users
dont have image previews in the FileOpenDialogs
Refactor all FileChoosers for a more simple approach when we use them
Add a new SendFileDialog, so we dont have to put widgets into the FileChooser
which forces non-native Dialogs.
This allows us to import the app module without triggering
dependency detection
Also add is_installed() for checking if a dependency is installed and
disable_dependency() in case we dont want to use a dependency
- init configpaths earlier so logging can access it to store debug logs
- First step for more consistency across Gajim when looking up paths
Recommended usage for the future:
app.configpaths.get()
configpaths.get()
- Complete rewrite of the old Groupchat dialog
- Has now a "minimal" mode, which is used if we have all infos for joining except the nickname and if we want to bookmark
- Handle xmpp uris received via command line
- Add support for Pubsub Avatars
- Dont poll for vCard Updates, only use XEP-0153
- Dont cache vCards
- Store the avatar SHA of roster contacts in the DB
- Store the current SHA of each contact in the Contacts Object
- Move some code into the ConnectionVcard Class
